Oh, man, those pix in the Wiki article bring back memories! We had a
360/30 mainframe at the high school I attended and was in the Comp Sci
program. I got to know our 1403 pretty well, and even made replacement
carriage control tapes (to the right in the open pic) for it when they'd
wear out; never punched one wrong, I believe. All the various alignment
knobs when changing forms to something like continuous feed labels or
different paper than the 132-char wide green bar.
Ancient history. Don't think ours automatically opened when it ran out
of paper, though. Might've been an option.
